I can compare the pitch of different sounds (high, low) produced by changing vibrations, length or tension.
Special Hint: Long objects--low pitch--slow vibrations Short objects--high pitch--fast vibrations Investigations
All sounds come from a source that is vibrating.
Anything that detects vibrations is a sound receiver.
Strong vibrations make loud sound volume.
Fast vibrations produce high-pitched sounds. Slow Vibrations produce low-pitched sounds.
Glossary Vibration- a rapid back-and-forth motion
Sound Source- an object or material that vibrates in a way that makes sound
Sound Receiver- something that detects sound
Volume- the loudness of a sound
Pitch- How high or low a sound is
Frequency- how we measure vibrations
Sound Discrimination- the ability to identify sounds as different from one another.
Amplify- to make a sound louder
Tension- the degree to which a material has been stretched
Students should be able to answer the following questions:
